UNITED STATES JOSEPH KOENIG, OF TWO RIVERS, WISCONSIN.

FISH-NET FLOAT.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed February 18, 1907. Serial No. 357,830.

To all whom, it may concern:

Be it known that I, J OSEPI-I KOENIG, a citizen of the United States,and a resident of Two Rivers, in the county of Manitowoc and State ofWisconsin, have invented certain new and useful Improvements in Fish-NetFloats; and I do hereby declare that the following is a full, clear, andexact description thereof.

The invention consists in what is herein shown, described and claimed;its object being to provide simple, economical fish-net floats of thetype disclosed in Patents No. 739,324, granted September 22, 1903, andNo. 780,041 and 780,042, granted January 17, 1905, the improved floatsbeing partitioned to stiffen them against external pressure and toprovide air-tight compartments whereby collapse of said floats isprevented and each of the same is not wholly impaired as to buoyancyunless all of its said compartments are punctured.

The accompanying drawing represents an improved fish-net float partly invertical longitudinal section.

Referring by numeral to the drawing, the float is shown as being apreferably seamless cylindrical air-tight shell 1 provided adjacent toits ends with outer annular grooves2 in which to fasten the cord bywhich the float is secured to a fish-net, the annular inner beads 3,counterparts of said grooves, and other annular inner beads 4 in pairsserve to strengthen said float.

Suitably held between each pair of the beads 4 of the float is apartition 5 that serves to resist external pressure that would otherwisecollapse said float. By means of a partition or partitions, the float isdivided into a plurality of air-tight compartments, all of whichcompartments must be punctured before the buoyancy of said float iswholly impaired, the number of partitions, one or more, being inproportion to the length of the aforesaid float.

The shell and its partitions,constituting the improved float, arepreferably of aluminium, said partitions being flat disks held in place,as aforesaid.

The successive steps in the manufacture of the float are as follows: Atube having. a round end is first drawn, the groove 2 and a groove 4 arethen rolled in the tube, a partition 5 positioned against the inner beadresulting from the formation of said groove 4, the two succeedinggrooves 4 are next rolled and as a result of this operation saidpartition is set tight in the tube, the next partition is now positionedand secured when the last grooves 4 and 2 are rolled, after which thetube is closed by spinning and welding operations.

I claim:

1. A fish-net float comprising an air-tight shell provided with pairedstrengthening beads, and a partition held between each pair of saidbeads.

2. A fish-net floatcomprising a seamless metallic shell having externalannular grooves adjacent its ends, paired strengthening ribs, and apartition held between each pair of said ribs.

In testimony that I claim the foregoing I have hereunto set my hand atTwo Rivers in the county of Manitowoc and State of Wisconsin in thepresence of two witnesses.
